Our Mission

It is the duty of the Tax Assessor-Collector to assess and collect for the County all taxes imposed on property within the county. The County Tax Assessor-Collector is designated by statute as the agent for the state Department of Highways and Public Transportation for collection of motor vehicle fees. Under the registration statutes, every owner of a motor vehicle is required to register it with the tax assessor in the county in which the owner resides. The County Tax Assessor-Collector is required to make bank deposits and reports according to the terms of several statutes. Under the laws regulating the county depository, the county tax collector is required to deposit all taxes collected by him for the state, county, or special districts for which he collects taxes.
